ApplicationBall Valves lined with PFA or FEP provide trouble free service in acid environments&comma; they are commonly used in pulp and paper operations&comma; Chlorine water&comma; Chlorine dioxide&comma; Sodium hypochlorite and sulphuric services&period;

Advantages&colon; L Integrated ball&sol;valve stem with anti- expulsion design&period; L The lining of valve and ball can provide the general chemical corrosion-resistance materials as PFA & FEP by requirements&period; L As for the innovative plate-type PTFE bellows filling structure&comma; it can automatically adjust between the movable filling gland ring and spring tableting&comma; and even though under the condition of heat-cool cycle&comma; the filling always has high leak tightness and reliability for pre-selection loading&period; L Even though on condition of frequent alternation between coldness and heat&period; It can realize the sealing effect for the flange of metal to metal mode&period; L It has unified lining thickness in the sealing area to promote the ability for resisting the permeable mediaL Strengthen the surface loading ability for labyrinth sealing through casting sealing lip&period; Carry long life PTFE valve seat&period; L It adopts special spring valve seat design to ensure permanent leak tightness within the range of the entire pressure&sol;temperature&comma; including in condition of vacuum&period; L It can choose the lining with antistatic property&period; L PFA and FEP thermo-plastic valve lining with 3&period;5 mm's thickness&comma; anti-seep&comma; anti-corrosion and anti-vacuum&period; L As for the high penetrability medium&comma; it can adopt 5mm's lining for the over-current part in the valve&period; Specifications
